The trial offers incentives through pharmacies in the form of vouchers to smokers who participate and stop smoking over a period of three months.

The trial was undertaken in the Glamorgan Spring Bay area in 2018.

About 34 per cent of the participants in that trial quit smoking after the program, adjunct researcher at UTAS Dr Mai Frandsen said those trial results were very good.

"Financial incentive programs are one of the most effective strategies for helping people to quit smoking," Dr Frandsen said.

"Last year's pilot program in Glamorgan Spring Bay illustrated how working with a community, in particular pharmacies, can help deliver and promote successful quit smoking programs."

The trial invites anyone from the George Town area who smokes to sign up for the trial at participating pharmacies.

Dr Frandsen said Aboriginal and Torres Strait Islander smokers can go to the Community House in George Town where a Flinders Island Indigenous Association officer can assist them if need be.

Over the three-month program participants will receive carbon monoxide tests regularly.

Those with low ratings will receive $50 vouchers provided by local businesses, one for each of the first four visits followed by one for each of the last two months of the trial.

With politicians debating whether to raise the legal smoking age in Tasmania to 21, Dr Frandsen said any avenue that could stop people smoking is worth exploring.

"I don't think we can discount any strategy," she said.

"Our best practice smoking cessation treatment we've got at the moment is a combination of nicotine replacement and behavioural support, and the 12-month success rate of that is seven per cent.

"When we recognise that most people take up smoking while they're young, before they hit 25 years, anything to discourage people from taking up smoking should be considered."
